Step 1: Enter User Permissions Management
Click on the campaign name in the upper right corner of the screen and select "Users"
Step 2: Add New User
Step 3: Add User Name and Email.
Email must be a Gmail or a Google-based email account.
Step 4: Select User Permissions Level**
Now you can assign your Users to specific Lists. If you assign a User to a List, that User can view only that List and create sublists and Efforts with that List/data. If you'd like to have multiple Users assigned to one List, simply add more Users which can be removed with the X mark.
